Answer:
530.66
Step-by-step explanation:
The way we find the area of the circle we use the radius of the circle for this one it's 13cm squared * pi or 3.14
For this circle we do 3.14 * 13^2
First we have to square 13: 13^2 = 169
Then we multiply 169 by 3.14: 3.14 * 169 = 530.66
Then we do to the nearest hundredth which is the same as the previous answer: 530.66
i know its the frist or second one i did the test i am also in flvs :)
Let's suppose we want to solve

with

. Separating variables and integrating, we get

Leaving the solution in this form, the initial condition gives

This means the solution is

.
Now if we were to write

, then we would have found

so that the solution would have been

.
But these two solutions are the same, since

. So we get the same solution regardless of where we place

, despite getting different values for

.
